Ta all whom, t may con-cern:

` Be it known that I, LEONARD H. DYER, a or citizen of the United States, residing in East Orange, county of Essex, State of New'Jer sey, have invented certain new and useful Improvements in Steering-Gear, of which the following is a speciication.

` The object I have in view is the production of a change-speed gearing for steering vessels or vehicles, but particularly the former, inwhich the change from speed to power, or vice versa, may 4be readily and surely effected and withoutthe use ofsliding or shift gearings or clutches. I attain these objects by the mechanism-illustrated in the accompanying drawings which show one embodiment of my invention, and in whichv simple form.'

Figure 1 is a top view of a steering-gear of section, taken on the lines 2 2 of ig. 1 and Fi 3 is a detail view of a modification.

n theviews like parts are designated by the'saine reference characters,

. gears In carrying out iny invention I provide a plurality of steering-wheels. As shown in the drawings', the wheell 1 is carried upon and rotates a shaft 2. Surrounding this shaft is a sleeve 3, carrying a second 'wheel '4. The which meshes with a gear 6. The sleeve 3 carries a larger pinion-7,

6 and 8 are carried by the quadrant 9, to which is attached the depending yoke 10,

which is secured to and actuates the steering member 11, `llustrated as a rudi'ler-stock. The uadrant 9 is pivcted at 12 to the frame his latter is support-ed, asshown, in proper relation to the steering member.

'A collar 16, engaging with the bearing 14, and-a collar 17, engaging withthe wheel 4 revent vlongitudiiiai movement of the sha t 2. The inner end ofthe sleeve 3. 'engages .with one face-of the pinion 5, preventing 'endwise movement of the sleeve `in one direction, while the engagement of, one'face of the pinion-7 with the bearing llwill prevent it in the other direction. The bearing or table 18 is rovided to give sup ort to the quadrant an prevent accidenta fdisplace'- nient of the gears by the teeth coming out of vfrom that secured by Fig. 2 is a side view, partially in. -more power.

which meshes with a gear 8. Both` Vvehicle may be controlle the vtwo with the pinions in proper posif Aor the vessel to get beyond the 'contro By iny invention this danger --is mesh when the gearing is subjectedto severe unusual strains. It' will be understood from theforegoing description that the two lwheels actuate the steering member, each through its own gearing, which is substantially independent of the other.

The speed reduction secured by means of the gearing which comprises the shaft 2,/ the pinion 5, and gear 6 is considerably4 different the sleeve 3, the'pinion 7, and the gear 8. The pinion 7 isso much larger than the pinion 5 that in spite of the increased radius of itsv engagin gearit will secure a much less reduction--t at is to say, it will move the ally greater epee than the other gearing, which of course will have proportionally .This speed reduction is suitrelation e lanation it will be seen between speed and-power.

that the wheel 1 wil actiiate gearing which vwill move the uadrant with greater power and less speed t an that actuated by the wheel 4., The

speed relationbetween the two gears may varied as nec'ess'ity requires, as is obvious.

The wheels 1 and 4 are preferably'placed sufiiciently close ear. The vessel or by means of one of the wheels under ordinary circumstances.

W'hen increased power or speed isrequired,

out losing control of the the use ofthe other wheel may be resorted to. By my invention I secure a gearing or use.

ing control of the vessel, vas is thecase where clutches or shifting gears are ern the loyed. r practice with former two-spes gears change is often made. only When vthe high-V speed gear no longer serves to keep the vessel y in control.

There will then be such a severe straint-.upon the gearin that to change rom the'high speed to the ears or clutches will make'it .extremely liable steersman avoided. Y i

In Sia modification is illustrated in which the pinion 5 is larger than tl'ilinion 7 In this strueti'ire the inner wheelow speedby shifting of the .foo
